摘要
为了获得细菌冶金的嗜高温细菌 ,取山西煤矿煤矸石堆的样品 .用选择培养基 ,5 0℃ ,pH2 5~ 3 0 ,恒温水浴摇床振荡培养 ,选择出了快速氧化Fe2 +为Fe3 +,对元素硫有较弱氧化能力 ,最适生长温度 5 5℃ ,最适pH2 3左右 ,专性自养生长的嗜热氧化亚铁菌株 .此菌在细菌冶金中具有一定潜力 .
To get the thermophile for bioleaching, the sample is taken from a heap of coal in Taiyuan Shanxi province. An obligate autotrophilc thermophile is isolated using the selective medium with the condition of 50℃, pH2\^3 in aerobic condition. Ferrous iron can be oxidized quickly and elemental sulfur weakly. The optimum temperature and pH of the bactium is 55℃ and about 2\^3 respectively. It is a potential strain in bacterial leaching.
